These meters are easy to operate using the convenient built-in Quick-Start Guide and only three function buttons. SMART STABILITY™ and SMART AVERAGING™ functions simplify measurement process. Accepts both 4- and 2-electrode cells.
Other features include automatic or manual temperature compensation; bright LCD display with ready indication; 200 point datalogger and RS-232 or USB interface; advanced self-tests; and mini DIN locking conductivity probe connectors. CE- and CSA-approved, UL-listed.
Orion 3-Star Benchtop Conductivity Meter is a single-channel meter that provides reliable and accurate conductivity, resistivity, salinity, TDS, and temperature measurements.
Orion 4-Star Benchtop pH/Conductivity Meter is a dual function, dual display pH/Conductivity meter that also measures resistivity, salinity, TDS and pH with 1 to 5 point calibration for pH and conductivity to ensure accuracy even at extremes of concentration. Additional features include a BNC pH electrode connector; automatic or manual pH calibration; auto-buffer recognition of DIN and NIST/US buffers; and GLP IQ/OQ documentation.
Kit includes: Benchtop Meter; Orion epoxy conductivity cell with 1.5 m cable; conductivity/TDS standard 1413 µS/cm (5 x 60 mL); electrode stand; and universal power adapter. 4-Star meter also includes a Triode™ pH/ATC combination electrode; pH 4.01, pH 7.00, and 10.01 buffers (475 mL); and pH electrode storage solution (475 mL).
